Engineer Brano Meres' experimental X-9 Nighthawk bike frame looks like some kind of a stealth bike. Its made with a lightweight carbon fiber skin that surrounds a core made from a material partially composed of Aramid, a synthetic fiber used in body armor fabric.

Its so light, that the X-9 frame weighs only three pounds. Is Brano planning to put this into production? He'd better! Brano's primary goal for the bike was to experiment with building a frame using the same honeycomb sandwich panel techniques as is used in the aircraft industry.
